Generally, it is okay, but it is recommended to heat the milk before drinking to avoid catching a cold. During menstruation, women can drink a cup of hot milk before going to bed each night, which can help with sleep and alleviate symptoms of painful menstruation. Dysmenorrhea is a common gynecological condition in women, characterized by pain in the lower abdomen, bloating, accompanied by backache or other discomforts before and during menstruation, which in severe cases can affect the quality of life. During menstruation, it is important to maintain a regular schedule, avoid staying up late, avoid consuming spicy and stimulating foods, and refrain from eating cold foods such as ice cream. It is also important to keep the abdomen warm, possibly using a hot water bottle to apply heat to the abdomen.
